★ The only tax holiday API built for ecommerce

Tell shoppers their cart is TAX FREE — and watch them buy.

TaxHoliday.app is the only API that tracks every US sales tax holiday and turns it into checkout messaging. Drop in our Shopify badge — or build your own — and show customers the moment a product ships tax-free. That's a 5–12% saving, surfaced right when they're deciding to buy.

The Opportunity
The easiest conversion
win you're not using

When an order qualifies for a sales tax holiday, your customer saves 5–12% — but only if they know about it. TaxHoliday.app puts that savings message in front of them at the exact moment they're deciding to buy. It's low-hanging fruit for any ecommerce store.

💸
A Real Reason to Buy Now
Tax holidays are time-limited. A clear "this is tax-free right now" badge creates urgency and pushes shoppers over the edge to checkout.
